Testing simulation of a road depicted in a testing environment turning into a real road When Field Testing Isn’t Possible, Use Simulation

Field testing is great for discovering different situations, but due to a variety of constraints, it may not always be possible. In such cases, simulation is useful to create a picture that mimics the real scenario. You can replicate hardware, operating systems, network ranges, and more, as well as nonfunctional areas.

Left arrow painted on a wall 5 Ways to Shift Performance Testing Left

Performance testing is often a barrier to accelerating software delivery. Because you need a production-like environment, performance testing often waits until the entire application is complete. But you shouldn't wait until then to get started. You can begin testing earlier to reduce rework and address issues sooner.
